APPENDICULAR SKELTON It consists of the shoulder girdle

APPENDICULAR SKELTON It consists of the shoulder girdle with the upper Limbs and pelvic girdle with the lower Limbs. Shoulder girdle It consists of 2 scapula and 2 clavicle. 1. Scapula #. It is a flat triangular shape bone locates on the posterior chest wall. #. Laterally the scapula has a cavity called as glenoid cavity to which head of the humerus attaches and forms the shoulder joint. #. On the posterior side there is a projection called as spine. #. The prominent point of the shoulder is called as acromion process, this joints with the clavicle and forms acromio clavicular joint.

) E N O B R A L L O C ( E CLAVICL #. It is a S shape long bone #. It locates on the lateral wall of the shoulder. #. It joins with the manubrium of the sternum and forms sterno clavicular joint, It also joins with the acromion process of the scapula and forms the acromio clavicular joint. #. The clavicle is the only bone that links axial and appendicular skeleton.

UPPER LIMBS HUMERUS #. It is the bone of upper arm. #. The head locates in the glenoid cavity of the scapula and forms shoulder joint. #. On the head of the humerus there is a projection called as greater and lesser tubercles. #. Between these two Tubercles the gap is called as biceptal grooves. #. The humerus distally attaches with radius and ulna to form elbow joint.

RADIUS AND ULNA #. These are the bones of the forearm. #. the ulna is longer than the radius. #. these two bones proximally connected with humerus and forms elbow joint and distally connected with carpal bones to form wrist joint.
